This World Space Week, we’re celebrating University of Surrey alumnus Doug Sinclair, who has spent his career helping small satellites make a big impact.
After completing his MSc in Satellite Engineering at Surrey in 1998, Doug went on to found Sinclair Interplanetary, a company that designed specialist spacecraft hardware used on more than 100 satellites. His work has contributed to missions and technologies including NASA’s CAPSTONE lunar mission and emergency messaging from the iPhone 14.
